python 使用装饰器并记录log的代码实例

   formatter = logging.Formatter('%(asctime)s %(levelname)-8s: %(message)s')

   file_handler = logging.FileHandler(log_path,encoding="utf8")
   file_handler.setFormatter(formatter) # 可以通过setFormatter指定输出格式
 
   # 控制台日志
   console_handler = logging.StreamHandler(sys.stdout)
   console_handler.formatter = formatter # 也可以直接给formatter赋值
 
   # 为logger添加的日志处理器
   logger.addHandler(file_handler)
   logger.addHandler(console_handler)
 
   # 指定日志的最低输出级别，默认为WARN级别
   logger.setLevel(logging.INFO)
  # 添加下面一句，在记录日志之后移除句柄
  return logger
